Vidu Q3 AD

[Core Function] Vidu Q3 AD is a keyframe-driven short-play (short drama) Image-to-Video model that turns a film-style script plus character, scene, and prop reference images into a complete multi-shot short video, automatically planning shots and compositing them in one pass. [Strengths] It excels at multi-shot narrative coherence and keeping referenced characters, scenes, and props consistent across shots, driven directly from keyframe reference images without manual shot-by-shot prompting. [Best For] Highly recommended for: short ad films and brand stories, scripted short dramas, multi-scene narrative clips generated from a script, and character-driven reels built from a small cast of reference assets. [Limitations] Do NOT use this model to simply animate a single image (use a standard image-to-video model such as Vidu Q3 Pro/Turbo I2V instead); it requires script_content in traditional screenplay format (scene + characters + dialogue) plus 1-14 reference assets each with an image_uri, outputs 1080p in 16:9 or 9:16, and does not expose per-shot duration or style controls (duration is auto-planned). Asset type must be one of character/scene/tool. [Routing] Choose Vidu Q3 AD when the user provides a script and reference images and wants an automatically directed multi-shot short drama from keyframes. For animating a single image into one continuous clip, route to viduq3-pro-i2v / viduq3-turbo-i2v; for the standard short-play flow with placement/quality/duration/style controls, route to Vidu Q3 Drama.
